InnovationHas A Name

Residential

The story is all in the details. Everywater heater

that carries theA. O. Smith namehas a reputation

to live up to, one that we’ve earned through

decades of innovations. As an industry leader, we

constantly look for newmaterials and develop

new technologies that can improve energy

efficiency. Even if it’s as basic as a valve, we

want tomake sure every component passes the

“best test.” So,when you choose anA.O. Smith

residential water heater, whether it’s gas, electric

or hybrid you can be confident that you are getting

the best water heating solution regardless of the

application—for today and for years to come.

Innovation has a name . . . A. O. Smith.

All A. O. Smith residential water heaters meet the FederalEnergy Efficiency Standards effective January 20, 2004, accordingto the National Appliance Energy Conservation Act (NAECA) of1992 and meet the thermal efficiency and standby lossrequirements of the U. S. Department of Energy and currentedition of ASHRAE/IESNA 90.1. They also comply with thecurrent edition of ICC Codes and the HUD Standards. Gas modelsmeet American National Standards Institute Standards (ANSIZ21.10.1 - CSA 4.1) governing storage-type water heaters.Electric models are UL listed according to safety specificationsoutlined in Underwriters Laboratories, Inc. Standards for Safety(UL 174).

CoreGard™ – Advanced AnodeRod Protection… An IndustryStandard!

The anode rod is a highly effective corrosionfighting systemwhich utilizes cathodicaction to protect internal tank surfaces fromcorrosive elements. CoreGard adds a stainlesssteel core tomagnesium or aluminumanodes for even longer life. Standard onConservationist® and ProMax®models.

Self-Powered ElectronicGas Valve

Series 300 A. O. Smith gas water heatersare equipped with a self-poweredelectronic gas valve with intelligent controllogic. The gas valve has an internalmicroprocessor that provides enhancedoperating parameters and tighterdifferentials for precise sensing and fasterheating response to optimize performance.The self-powered electronic gas valve usesa thermopile to generate the powerneeded to operate the electronic gascontrol without requiring an externalpower source It also incorporates an LEDStatus Indicator that monitors systemoperation and service diagnostics.

PEX Dip Tubes

A. O. Smith’s PEX cross-linked polymer diptubes are long-lasting with superiorresistance to destructive thermal oxidation.Standard on all gas and electric models.

Blue Diamond® Glass Coating

Provides superior corrosion resistancecompared to industry-standard glasslining.

CSA® - Low Lead Content

This mark shown on a plumbing productsignifies certification to California’slegislative AB 1953 and Vermont’s legislationAct 193 that limits the lead content inplumbing fixtures that come in contact withdrinking water to a maximum of 0.25% lead.

Residential Water HeaterSelection Guide

4

To select the right A. O. Smith water heater for your home, you need to consider the size of your family and other factorsthat contribute to your First Hour Rating (FHR) Requirement. The charts below provides suggested A. O. Smith ResidentialWater Heater selection guidelines for several family sizes.

TANK-TYPE MODELS1. Determine whether your family is Low Demand or High

Demand. You should consider your family to be HighDemand if…

� There are more than two full baths in the home.

� There are (or will be) teenagers living in the home. It’s afact: teenagers use more hot water for showering andwashing clothes.

� You have an oversize whirlpool bath or other large tub.As a rule of thumb, the water heater tank capacityshould be 100% of the bathtub capacity (example:75-gallon tub / 75-gallon water heater).

2. Locate your Family Size and determine the First HourRating Requirement for your family. If you decide yourfamily is High Demand, consider moving up to the next FirstHour Rating level.

3. Consult the heater options on the following pages for anA. O. Smith residential water heater with a First HourRating that meets your requirements.

HEAT PUMP MODELSElectric Heat PumpWater Heaters operate at peak-efficiencywhensized to allow slower reheating ofwater. For this reason, definewater heating sizing based on “HighDemand” criteriawhendetermining First Hour Rating for an electric heat pumpwater heater.

Average Ground WaterTemperature: 62°F to 77°F

TANKLESS MODELS

Remember, these are general recommendations. Your A. O. Smith Water Heater Specialist can review your family’s needs in even greater detail tomake sure the model you choose will always provide enough hot water to meet the demand.

MATCH THE UNIT TO YOUR NEEDSNumber of showers each A. O. Smith unit can handle,

depending on ground water temperature

PEAK HOT WATER DEMAND

The next step is to determine howmuch hot waterwill be required during the busiest usage period(“peak demand”). Consider all appliances andfixtures that use hot water, including lavatoryfaucets, kitchen faucets, washing machines,dishwashers, showers and bathtubs. Be sure todetermine howmany appliances and fixtures willbe used at the same time (“peak demand”).

GROUNDWATER TEMPERATURE FACTOR

The temperature of incoming ground water (coldwater inlet temperature) varies greatlythroughout the U.S. and also fluctuates with thechanging of the seasons. The temperature ofwater as it enters the water heater will determinethe amount of “temperature rise” required toachieve the desired hot water outlet temperature(120°F is recommended).

The best way to measure your incoming groundwater temperature is to use a thermometer tomeasure cold water temperature during thecoldest season of the year. To simplify the process,use this map to determine whether yourinstallation location is in the Southern Zone,Central Zone or Northern Zone.

Specialty VentSpecialty vent gas water heaters are an alternative to standard metal vent water heaters.They provide venting flexibility in replacement applications and offer useful choices forlocation of gas water heaters in new homes. Specialty-vent benefits include:

Flexible Installation – Horizontal venting options allow tremendous flexibility for placementof the water heater in the home. A. O. Smith’s ProMax® power vent and power direct ventmodels offer various venting options and use inexpensive PVC, CPVC or ABS pipe. Seespecification sheets for venting distances.

Direct-venting for proper combustion – Insufficient indoor ventilation can deprive a gaswater heater of enough air for proper operation. The power direct vent and direct ventwater heaters have “two-pipe” systems that vent to and draw air from outside the home,eliminating concerns about indoor ventilation.
